我们为面板数据开发了一个广义动态因子模型,目的是估计未观察到的指数。 虽然在动态因子分析的文献中已经开发了类似的模型,但我们的贡献是三方面的。 首先,与在每个时间段测量同一主题的多个属性的简单动态因素分析相反,我们的模型还考虑了多个主题。 因此它适用于面板数据框架。 其次,我们的模型为每个时间段的每个受试者估计了一个独特的未观察到的指数,这与之前使用所有受试者通用的时间指数的工作相反。 第三,我们开发了一种新颖的迭代估计过程,我们称之为两周期条件期望最大化 (2CCEM) 算法,并且足够灵活以处理各种不同类型的数据集。 该模型应用于测量与供水和卫生设施运营相关的属性的面板上。

经典著作,不用多介绍了。 Most tasks require a person or an automated system to reason--to reach conclusions based on available information. The framework of probabilistic graphical models, presented in this book, provides a general approach for this task. The approach is model-based, allowing interpretable models to be constructed and then manipulated by reasoning algorithms. These models can also be learned automatically from data, allowing the approach to be used in cases where manually constructing a model is difficult or even impossible. Because uncertainty is an inescapable aspect of most real-world applications, the book focuses on probabilistic models, which make the uncertainty explicit and provide models that are more faithful to reality. Probabilistic Graphical Models discusses a variety of models, spanning Bayesian networks, undirected Markov networks, discrete and continuous models, and extensions to deal with dynamical systems and relational data. For each class of models, the text describes the three fundamental cornerstones: representation, inference, and learning, presenting both basic concepts and advanced techniques. Finally, the book considers the use of the proposed framework for causal reasoning and decision making under uncertainty. The main text in each chapter provides the detailed technical development of the key ideas. Most chapters also include boxes with additional material: skill boxes, which describe techniques; case study boxes, which discuss empirical cases related to the approach described in the text, including applications in computer vision, robotics, natural language understanding, and computational biology; and concept boxes, which present significant concepts drawn from the material in the chapter. Instructors (and readers) can group chapters in various combinations, from core topics to more technically advanced material, to suit their particular needs.
